The 23-year-old actress, who has previously denied rumours of an off-screen romance with Leo, told the New York Post that her sex scenes with Leo were "the least romantic thing".

"The whole thing ended up being quite comical," Margot revealed. "We [had to] entice this dog to jump in the bed and bite at Leo's feet … so we had dog trainers at the end of the bed [with] dog treats … we're putting chicken liver on Leo's toes. We're in a small room, it's hot, it's sweaty, it smells like dog food."

A recipe for sexual chemistry, right? To put it in context, Leo plays dodgy New York stockbroker Jordan Belfort, who gets it on with beauty Naomi Lapaglia (Margot) with a barking dog on their bed. Watch the trailer above for a peek!

Leo and Margot joined their co-stars, including Jonah Hill and Matthew McConaughey at the Wolf of Wall Street premiere on Tuesday in New York.
